Our invention relates to the prefumery uses of methyl-substituted 1(2-norbornyl) alkanol acetate esters defined according to the structures: ##STR3## and intermediates for producing such esters including the alkanols defined according to the structures: ##STR4## as well as organometallic compounds defined according to the structures: ##STR5## wherein M' is MgX or Li and wherein X is chloro, bromo or iodo.
Chemical compounds which can provide seashore, ozoney, fruity, dry orange peel, bergamot and fatty aromas with rose, fatty, buttery, seashore and dry orange peel topnotes are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the essential fragrance notes provided by natural essential oils or compositions thereof having the above properties. Unfortunately, many of these synthetic materials either have the desired nuances only to a relatively small degree or else contribute undesirable or unwanted odor to the compositions.
Methyl-substituted norbornyl esters are shown to be useful in the art of perfumery by Light, et al, U.S. Pat. No. 4,076,853 wherein such esters are defined according to the structure: ##STR6## wherein R1 represents hydrogen or lower alkyl; R2 represents hydrogen or lower alkyl; R3 represents hydrogen or lower alkyl; and n is zero or one. At columns 41 and 42, lines 1-5, Light, et al also discloses for use in perfumery the compound having the structure: ##STR7## which is indicated to have a "camphoraceous, woody and green aroma with minty nuances". Schleppnik, I, U.S. Pat. No. 3,942,761 discloses the genus of compounds having the structure: ##STR8## wherein R represents hydrogen or lower alkyl and R1 represents hydrogen or methyl, for use in perfumery. Schleppnik, II, U.S. Pat. No. 3,803,244 discloses the compounds having the generic structure: ##STR9## for use in perfumery wherein R and R2 represent lower alkyl; and wherein R1 represents hydrogen or methyl. Schleppnik, III, U.S. Pat. No. 3,780,109 discloses the genus of compounds having the structure: ##STR10## for use in perfumery wherein R1 is hydrogen or methyl and R represents lower alkyl.
Schleppnik, IV, Chemical Abstracts, Volume 90:121081 (abstract of U.S. Pat. No. 4,128,509) discloses specifically the compound having the structure: ##STR11## for use in perfumery. However, Schleppnik, IV, or any of the other references, do not infer mixtures of the compound having the structures: ##STR12## for use as intermediates in preparing esters defined according to the structures: ##STR13## Furthermore, Schleppnik, IV does not disclose the alcohol defined according to the structure: ##STR14## but only the alcohol having the structure: ##STR15## Arctander, Perfume and Flavor Chemicals (Aroma Chemicals), Volume I, published in 1969, discloses at monograph 1029 the norbornyl ester having the structure: ##STR16## for use in perfumery. Arctander indicates: "Mild and sweet-woody odor with a floral-piney undertone. The commercial products are probably not very well-defined single chemicals, and great variations in odor have been observed.
This ester has been developed in line with the research on Sandalwood type odors. The parent alcohol "Camphene carbinol" was once considered useful as a Sandalwood type material, but it has found more use as a sweetening and enriching ingredient in sophisticated Pine fragrances. The title ester finds limited use in perfume compositions of woody character, Fougeres, Pine fragrances, etc. and it blends very well with the Cyclohexanol derivatives, Ionones, iso-Bornylacetate, Nitromusks, etc."
None of the foregoing references, including the Schleppnik references I-IV, Arctander or the Light, et al reference, discloses or infers the existence of the compound having the structure: ##STR17## or the compound having the structure: ##STR18## or the compound having the structure: ##STR19## Furthermore, nothing in the prior art discloses for use in perfumery the compound having the structure: ##STR20## or the compound having the structure: ##STR21## which have unobvious, unexpected and advantageous properties.

Referring to FIGS. 21 and 22, in particular, the apparatus used in producing polymeric fragrances containing at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention comprises a device for forming scented polyolefin (for example) pellets which comprises a vat or container 212 into which a mixture of polyolefins such as polyethylene and an aromatic substance or scented material is placed (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention). The container is closed by an airtight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an airtight manner and is rotated in a suitable manner. A surrounding cylinder 212 having heating coils 212A which are supplied with electric current through cable 224 from a rheostat or control 216 is operated to maintain a temperature inside the container 212 such that polyethylene or other thermoplastic polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ a colorless, odorless polymer (e.g., polyethylene) with a viscosity ranging between 180 and 220 Saybolt seconds and having a melting point in the range of 200°-280° F. The heater 212A is operated to maintain the upper portion of the container 212 within a temperature range of from 250°-350° F. The bottom portion of the container is heated by means of heating coils 212A heated through a control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container within a temperature range of from 250°-350° F.
Thus, polymer (e.g., polyethylene) is added to container 212 and is heated from 10-12 hours whereafter a scented aroma imparting material (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) is added quickly to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed.
Generally, about 5-30% by weight of the scented material (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) is added to the polyolefin.
After the scent imparting material (e.g., a composition containing at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) is added to the container 212; the mixture is stirred for a few minutes, for example, 5-15 minutes; and maintained within the temperature range as indicated previously by heating coils 212A. The controls 216 and 220 are connected, respectively, through cables 214 and 222, respectively, to heating coils 212A. The said controls 216 and 220 are also connected through cables 224 and 226, respectively, to a suitable power supply of electric current for supplying the electric power to the heating coils 212A for heating purposes.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 218/232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 218/232 is closed so that the liquid polymer (e.g., polyolefin) and aroma imparting material (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) will continuously drop through orifices 234 downwardly from conduit 232. During this time, the temperature of the polymer (e.g., polyethylene or polyolefin) and scent imparting material (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) is accurately controlled so that a temperature in the range of from about 210°275° F. will exist in the conduit 218/232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer (e.g., polyethylene) and scenting material (e.g., at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention) mixture through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 245 and utilized in processes as illustrated, infra.
A feature of this aspect of the process of our invention is the provision for moistening of the conveyor belt 238 to insure rapid formation of the solid polymeric (e.g., polyolefin) scented pellets 244 without sticking to material which will normally stick to a melted plastic. A moistening means 248 insures a sufficiently cold temperature of the belt surface for adequate formation of the pellets 244. The adequate mositening means comprises a container 250 which is continuously fed with water 254 to maintain a level for moistening a sponge element 256 which bears against the exterior of the belt 238.
We have determined that certain methyl-substituted 1(2-norbornyl) alkanol acetate esters defined according to the structures: ##STR62## are capable of imparting a variety of fragrances to various consumable materials and are also capable of augmenting or enhancing a variety of fragrances of various consumable materials. Preferably, our invention is directed to:
(i) solely to the compound having the structure: ##STR63## and its use in perfumery; (ii) to the mixture of compounds having the structures: ##STR64## and the use of such mixture in perfumery; (iii) the compounds having the structures: ##STR65## as intermediates for preparing the ester of (i) and (ii); and (iv) the chemical intermediates defined according to the structures: ##STR66## where M' represents MgX or Li and wherein X represents chloro, bromo or iodo.
Specifically, the genus having the structure: ##STR67## is intended to include the compound having the structure: ##STR68## The genus having the structure: ##STR69## is intended to include the compound having the structure: ##STR70## Our invention also includes the alkali metal salts defined according to the structure: ##STR71## and also shown by the structure: ##STR72## wherein M represents alkali metal, such as sodium or potassium or alkaline earth metal, such as barium; and P is the valence of M, for example, 2, in the case of M being barium.
It is contemplated that our invention also covers the stereoisomers of the compound having the structure: ##STR73## or mixtures of the compounds having the structures: ##STR74## wherein Z is hydrogen or acetyl, to wit: the configurations having the structures: ##STR75## wherein the asterisks (*) are indicative of asymmetric carbon atoms. Thus, for example, it is contemplated that our invention covers the particular stereoisomer, to wit: ##STR76##
Briefly, our invention contemplates augmenting or enhancing the fragrances of consumable materials, such as perfumes, perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, dryer-added fabric softeners and cosmetics) and colognes by adding thereto a small but effective amount of at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters defined according to the structures: ##STR77## including but not limited to the single material having the structure: ##STR78## and mixtures of compounds having the structures: ##STR79##
The methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention augment or enhance or impart seashore, ozoney, fruity, dry orange peel, bergamot and fatty aromas with rose, fatty, buttery, seashore and dry orange peel topnotes to perfumes, perfumed articles such as anionic, nonionic, cationic or zwitterionic detergents, dryer-added fabric softener articles, hair preparations and colognes.
The methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention can be produced using two routes. A first route will prepare a mixture of the compounds having the structures: ##STR80## and the second route will only produce the compound having the structure: ##STR81##
With respect to the route producing the mixture of compounds having the structures: ##STR82## vinyl norbornene having the structure: ##STR83## is used as a starting material. It is hydrogenated using a standard hydrogenation catalyst such as palladium on carbon or Raney nickel at a temperature in the range of from about 25° up to about 40° C. and at a pressure of less than about 50 pounds per square inch gauge according to the reaction: ##STR84##
The resulting product having the structure: ##STR85## is then reacted with a mixture of carbon monoxide and hydrogen (via an "oxo" reaction) using a standard "oxo" reaction catalyst known to those skilled in the art, such as:
[RuCl3 ·PCl3 ].
The "oxo" reaction is carried out at a temperature in the range of 110°-120°C and a pressure in the range of from about 500 up to about 700 psig. The reaction is shown thusly: ##STR86## wherein in the resulting mixture, the ratio of the compound having the structure: ##STR87## to the compound having the structure: ##STR88## is about 85:15.
The resulting mixture of compounds having the structures: ##STR89## is then reacted via a Grignard reaction with the compound:
CH3 -M'
which represents either methyl lithium or a methyl magnesium halide such as methyl magnesium chloride, methyl magnesium bromide or methyl magnesium iodide. The reaction is carried out under standard Grignard reaction conditions using a solvent such as diethyl ether, tetrahydrofuran or a mixture of tetrahydrofuran and toluene. The reaction is carried out at a temperature in the range of from about 30° up to 40°C, whereupon the organometallic compound mixture is formed which is a mixture of compounds having the structures: ##STR90## wherein M' represents Li or MgX and wherein X is chloro, bromo or iodo. The resulting mixture of compounds having the structures: ##STR91## is then hydrolyzed in aqueous acid such as aqueous hydrochloric acid or aqueous acetic acid. The reaction sequence including the oxo reaction and subsequent Grignard reaction and hydrolysis reactions is set forth as follows: ##STR92##
When using a methyl magnesium halide Grignard reagent, the Grignard reaction and subsequent hdyrolyses are as follows: ##STR93## or, more specifically: ##STR94##
When using methyl lithium rather than a methyl magnesium halide, the reaction sequence is as follows: ##STR95##
The resulting mixture of compounds having the structures: ##STR96## is then acetylated using standard acetylation reagents such as acetic anhydride or acetic acid in the presence of an acid catalyst. The treatment with the acetic anhydride or acetic acid is carried out under reflux conditions in the presence of a nonreactive solvent such as toluene. The mole ratio of acetylation reagent:alcohol reagent (mixture of compounds having the structures: ##STR97## is about 1.2:1 (mole ratio). The time of reaction is between about 1 hour and about 5 hours. This acetylation reaction is shown thusly: ##STR98## At the end of the reaction, the reaction mass is "worked up" by means of neutralization of the excess acetylating reagent using, for example, dilute aqueous sodium bicarbonate solution. The resulting product is fractionally distilled yielding product distilling at a vapor temperature of about 115°C and a pressure of about 1.5 mm/Hg.
The second reaction sequence gives rise to the preparation of, solely, the compound having the structure: ##STR99## In this second reaction sequence, the starting material is the compound having the structure: ##STR100## This compound is reacted with acetone under "aldol condensation" conditions according to the reaction: ##STR101## or according to the reaction: ##STR102## wherein M represents alkali metal or alkaline earth metal and P is the valence of the element indicated by M. Thus, for example, a useful base is barium hydroxide or barium oxide; however, sodium hydroxide and potassium hydroxide can also be used in order to catalyze the aldol condensation. The resulting salts shown by the structures: ##STR103## are novel materials. The resulting salts are then hydrolyzed in the presence of acid (and simultaneously dehydrated) to yield the mixture of ketones defined according to the structures: ##STR104## according to the reaction: ##STR105## The reaction is carried out under reflux conditions for a period of between about 4 and about 10 hours. The weight ratio of base catalyst to reaction mass is between about 1:100 and about 1:300. The base, such as barium hydroxide, is used in the presence of water and the concentration of base in water is about 20-30 grams per liter. The resulting product containing the compounds having the structures: ##STR106## contains about 30% of the compound having the structure: ##STR107## and about 70% of the compound having the structure: ##STR108## The resulting mixture of compounds shown thusly: ##STR109## is then hydrogenated using a Raney nickel catalyst or copper chromite catalyst according to the reaction: ##STR110## in order to yield the substantially pure alcohol having the structure: ##STR111## The hydrogenation reaction is carried out in the presence of an inert solvent such as isopropyl alcohol at a temperature of approximately 150°C and at a pressure of approximately 500 psig. In place of isopropyl alcohol or in addition thereto, it is preferable to include toluene as a solvent. The weight ratio of copper chromite catalyst:mixture of compounds having the structures: ##STR112## in this hydrogenation reaction may vary from about 1:100 up to about 2:100. The weight ratio of catalysts such as copper chromite catalyst:solvent (such as isopropyl alcohol) may vary from about 1:9 up to about 1:12.
At the end of the hydrogenation reaction, the reaction mass is "worked up" by means of appropriate washing and distillation. The resulting distillate is then reacted with an appropriate acetylation reagent, such as acetic anhydride or acetic acid in the presence of an acid catalyst, according to the reaction: ##STR113##
The resulting product is then "worked up" (whereby the excess acetylation reagent is neutralized with, for example, a dilute aqueous sodium carbonate solution) and is then fractionally distilled at a vapor temperature of about 100°C and at a pressure of 0.8 mm/Hg.
Examples of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention and their organoleptic characteristics are as follows in Table I:

As olfactory agents, the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention can be formulated into or used as components of a "perfume composition" or can be used as components of a "perfumed article" or the perfume composition may be added to perfumed articles.
The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols, aldehydes, ketones, nitriles, ethers, lactones, natural essential oils, synthetic essential oils, esters other than the esters of our invention and frequently hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. Such perfume compositions usually contain: (a) the main note or the "bouquet" or foundation stone of the compositions; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation, and substances which retard evaporation; and (d) topnotes which are usually low-boiling, fresh-smelling materials.
In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of the effects of each of the ingredients. Thus, the individual compounds of this invention, or mixtures thereof, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention which will be effective in perfume compositions depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.5% of at least one of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention, or even less, can be used to impart interesting, long lasting and substantive seashore, ozoney, fruity, dry orange peel, bergamot and fatty aromas with rose, fatty, buttery, seashore and dry orange peel topnotes to soaps, liquid and solid anionic, nonionic, cationic or zwitterionic detergents, cosmetics, powders, liquid and solid fabric softeners, optical brightener compositions and other products. The amount employed can range up to 50% or higher and will depend on considerations of cost, nature of the end product, and the effect desired on the finished product and the particular fragrance sought.
The methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention can be used alone or in a perfume composition as an olfactory component in detergents and soaps; space odorants and deodorants; perfumes; colognes; toilet waters; bath salts; hair preparations such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powder and the like. When used as an olfactory component of a perfumed article, as little as 0.01% of one or more of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention will suffice to impart an interesting, long lasting and substantive seashore, ozoney, fruity, dry orange peel, bergamot and fatty aroma with rose, fatty, buttery, seashore and dry orange peel topnotes. Generally no more than 0.5% is required. Thus, the percentage in perfumed articles of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention ranges from 0.01% up to about 0.5% based on the weight of the perfumed article.
In addition, the perfume compositions of our invention can contain a vehicle or carrier for one or more of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention, taken alone or taken together with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol or the like. The carrier can be an absorbent solid such as a gum or components for encapsulating the composition such as gelatin which can be used to form a capsule wall surrounding the perfume oil by means of coacervation.
It will thus be apparent that one or more of the methyl-substituted 1(2-norbornyl) alkanol acetate esters of our invention can be utilized to alter, modify, augment or enhance sensory properties, particularly organoleptic properties such as fragrances of a wide variety of consumable materials.
The following Examples serve to illustrate our invention, and this invention is to be considered restricted thereto only as indicated in the appended claims.
All parts and percentages given herein are by weight unless otherwise specified.
